Definitions

  • the invention relates to cellular telecommunications systems, in particular to the assignment of cell configuration parameters by a network element.
  • the amount of traffic which is served by a cell can be modified by assigning users in the overlap area between two cells to one or the other of these two cells. In other words, there is a certain overlap or border area between two cells where the mobile terminal may be served by any of these two neighboring cells. Via an intra-system handover mechanism, mobile terminals can be assigned to the desired cell.
  • One mobile terminal is handed over from one cell to another according to the handover parameter settings in combination with the actual radio link conditions from the serving cell in comparison to neighbor candidate cells.
  • the handover configuration settings controlled how early or how late the mobiles are handed over from one cell to another.
  • the invention provides for a network element of a cellular telecommunications system, a method of assigning a set of class-specific cell configuration parameters for a user service request, and a computer readable storage medium in the independent claims. Embodiments are given in the dependent claims.
  • a difficulty with state of the art systems is that there is currently no solution for doing service type specific load balancing between LTE cells because there is currently only one single set of handover configuration settings for one cell (Time To Trigger TTT, Handover Margin HOM and the measurement filter coefficient) and one single "cell individual offset” (CIO) or Offset Cell index-number (OCn) towards each neighbor defined in 3GPP LTE.
  • These handover settings apply to all users, i.e. independent of the service of the users.
  • Embodiments of the invention may address this problems by providing for a network element which assigns a classification to a user service request. A set of class specific cell configuration parameters are then assigned to be used for the provision of the telecommunications service.
  • Embodiments of the invention may comprise several parts which provide the necessary functionality for service class dependent load balancing and the signaling requirements to allow its powerful self organization, i.e. on a semi-static time scale.
  • LTE Long Term Evolution
  • service classes which define a certain set of service requirements, like e.g. real-time/non-real-time, amount of guaranteed data rate, delay requirements, ...
  • this set of requirements corresponds to a typical kind of application, e.g. voice telephony, video streaming, internet-surfing, etc.
  • not all users are treated in the same way. It is proposed to set different handover parameters for the mobile users.
  • relevant users could be grouped together and a certain set of handover parameters could be set for those users which belong e.g. to a certain service class.
  • the system has the possibility to initiate a handover to a neighbor earlier or later in order to carry out load balancing for distinct, well suited services or to exclude non or less suited services from load balancing.
  • the system can assign a particular type of users and/or services to the desired cell.
  • the type of users may refer to a user classification or a user profile.
  • embodiments of the invention may have mechanisms to control how to assign users best and selectively, i.e. depending on certain service classes, to the best suited cell, and to arrange the users in the border area in such a way that the system can achieve the optimal benefit.
  • the system can benefit when one cell serves this large user, while at the same time it can move some of its other users to a neighboring cell in order to free some resources which may be needed for that large user.
  • the required functionality of some embodiments of the invention i.e. the signalling information exchange, which may be needed to allow the system, to find out which service class dependent user assignment shall be achieved for the optimal system performance.
  • Handover parameter settings can be be coordinated between two neighboring cells. I.e. when one of the two cells initiates a handover earlier then the other cell could keep their mobiles longer before starting the handover procedure to the first cell. If there may be no coordination, between the two cells, then the following unwanted effects occur: If both cells initiate to hand over their mobiles earlier, then the mobile users tend to ping-pong between the two cells. Each cell tends to send away their mobiles in the common border area. If both cells keep their mobiles longer, then both cells can to invest unnecessarily a larger amount of radio resources (because a more robust coding is may be needed for the larger basestation to mobile distance). Both of those effects reduce the system performance and are not desired. (To be precise, it can also occur the situation, that only one cell varies its handover parameters, then the resulting effects are a mixture with partial effects of the above problems). So a coordination between cells may be beneficial, which thus could requires some signaling information exchange:
  • the decision entity may require the relevant cell load information of those cells, between which it decides how to arrange the resources in an optimal way, i.e. by setting the handover parameters.
  • This particular cell load information may be exchanged via signaling interfaces, as it is currently specified in 3GPP, but there only for cell-global load information values, it does not distinguish any separate values for specific service classes.
  • This invention proposes to exchange more detailed cell load information, i.e. service class dependent ones, as outlined below.
  • the cells may have information about the current handover parameter settings in those neighboring cells with which the handover settings are coordinated.
  • the information is provided and set via the central O&M system.
  • the trend goes towards distributed decisions, decentralized inside the basestations, and for this fully distributed approach the information is exchanged directly between the basesations.
  • This information exchange could be achieved e.g. via dedicated information about which handover settings are used.
  • the exchanged information i.e. the cell load information and the information/command about particular handover settings
  • the exchanged information may carry individual information for those service classes which are treated separately. This means, that when for example n (groups of) service classes are handled separately, that then specific cell load information values for (at least) these n (groups of) service classes may be exchanged, and that the handover parameter settings may be exchanged for these n (groups of) service classes.
  • This detailed information exchange about the load and settings of different service classes allows managing service class dependent load balancing.
  • an intelligent self organizing network (SON) algorithm has then the information basis to find those handover parameters for each service class which achieve the maximal benefit, like to maximize the user Quality of Service and to optimize the system resource usage.
  • SON intelligent self organizing network
  • the invention provides for a network element of a cellular telecommunications system.
  • a network element as used herein encompasses a computing device attached to a network of the cellular telecommunications system.
  • the network element is adapted for communicating with other components of the cellular telecommunications system.
  • the network element comprises a classification means for assigning a classification to a user service request for a telecommunications service of the cellular telecommunications system.
  • the network element further comprises an assigning means for assigning a set of class-specific cell configuration parameters that are to be used for the provision of the telecommunications service.
  • the assignment of the class-specific cell configuration parameters may depend upon the classification.
  • the user service request may be for one of a variety of different services. For instance the user service request may request voice, web browsing, streaming video, a video gaming service, voice over IP or a video call.
  • the classification may also encompass a user class or a user classification of the service request. In other words, users may have different priories assigned to them for different classifications of services. This allows different user classes or user classifications to be tailored to specific needs.
  • a user class for businesses may specify a high priority or level of service for voice communications and a low level of priority for web browsing.
  • a retail customer could be assigned a user class which give a high priorty to online games and internet surfing but a lower priority to voice communications. For the retail customer occasionally loosing voice communications may be acceptable, but for business customers it may not..
  • This classification could also be used for classifying a user service request.
  • the cell configuration parameters as used herein encompasses parameters which are produced to control the interaction of a user equipment with a cellular telecommunications cell and/or to control the interaction between two cellular communications cells. This is advantageous because instead of a single set of cell configuration parameters being used for all user equipment attached to the cellular telecommunications system the cell configuration parameters are assigned to a user service request depending upon its classification. In some embodiments, the cell configuration parameters are assigned to groups of user service requests. This may allow the more efficient allocation of bandwidth by a specific cell. For example, if several users are downloading internet data with their user equipment their downloading of data may be delayed slightly without a noticeable effect in their level of quality of service. However, one making a live voice or video conference would instantly notice a degradation in the level of service from the cellular telecommunications system.
  • the classification is assigned at least partially according to a service class of the user service request.
  • the user service request is assigned according to the type of usage that is requested in the user service request.
  • a 'service class' as use herein encompasses a classification of the type of data exchanged between a user equipment and the cellular telecommunications system.
  • the classification is assigned at least partially according to a user class assigned to the user service request.
  • the user class is associated with a user profile. For instance an operator of a cellular telecommunications system could sell contracts for usage of the system which have different levels or guarantees of service. For instance there could be gold, silver and bronze users of the cellular telecommunications system.
  • the network element further comprises a message receiving means for receiving a load message from a cell. If the network element is incorporated into the cell for instance as part of a base station or a node B then the message receiving means may be implemented via software where a message is passed from one software module to another. In other embodiments the network element is a distinct computing device which may in some embodiments receive a message via the cellular telecommunications system's internal network.
  • the load message could be a conventional load message which summarizes the total load on the cell or the load message could comprise the cell load classified by service class and/or user classes and/or information related to user equipment related measurement reporting events.
  • the load message is descriptive of the usage of the cell.
  • the load message is descriptive of the cell configuration parameters of the cell.
  • the cell configuration parameters of the cell could be class specific cell configuration parameters. In other embodiments the cell configuration parameters of the cell are not class specific.
  • the load message comprises the cell load classified by service classes and/or user classes.
  • the load message may simply contain a table or array which provides the cell usage by various service classes and/or user classes. In some embodiments, this could be a two or three-dimensional table or array.
  • the network element further comprises a modification means for modifying the set of class-specific cell configuration parameters using the load message.
  • the cell configuration parameters can be adjusted for any or all of the other users connected to the cellular telecommunications system.
  • This embodiment is particularly advantageous because modifying the set of class-specific cell configuration parameters allows load balancing with the cell and its neighbors.
  • Both the message receiving means and the modification means may in some embodiments be implemented as software.
  • the message receiving means may also be implemented as a hardware component. In some embodiments the message receiving means may allow the network element to communicate with an internal or external network of the cellular telecommunications system.
  • the message receiving means is adapted for receiving an neighboring cell load message descriptive of the usage of cells neighboring the cell.
  • the wording 'cells neighboring the cell' as used here may refer to cells which are physically adjacent to each other, to cells which are within a predefined geographical distance between each other, cells which are in a predefined neighborhood, or are connected by a communications network. In other words it is not necessary for cells to have overlapping service regions for cells to be considered to be neighboring. In managing a cellular communication network it may be beneficial to consider not just the load of not just cells which have overlapping service regions but also cells which in the same region or neighborhood. For instance if the handover parameters are adjusted for user equipment in a cell this may affect load balancing in cells which share overlapping service regions with that cell.
  • the neighboring cell may be any cell able to exchange messages with the network element.
  • the neighboring cell may be a cell which may have a network connection to the network element.
  • the neighboring cell load message comprises the cell load of the cells neighboring the cell classified by the user classes.
  • the network element further comprises a load balancing means for load balancing the base station using the load message and the neighboring cell load message.
  • the load balancing means uses load of the cell and an neighboring cell to balance the load between the two cells. This embodiment is advantageous because the cell configuration parameters are divided according to classes.
  • the cells may comprise information about the current handover parameter settings in those neighboring cells with which the handover settings are coordinated.
  • the message receiving means is adapted for receiving updated load messages and updated neighboring cell load messages.
  • the modification means is further adapted for dynamically updating the set of class-specific cell configuration parameters using the updated load messages and the updated neighboring cell load messages. This embodiment is particularly advantageous because the load of the cell and the neighboring cell will not be constant. Users may change their usage of a user equipment connected to the cellular telecommunications system. Also users may leave or enter the cell or the neighboring cell. It is therefore advantageous to dynamically update the set of class-specific cell configuration parameters.
  • the network element further comprises a user equipment messaging means adapted for exchanging messages with a user equipment which originated the user service request.
  • the user equipment messaging means is a component of the network element.
  • the user equipment messaging means is further adapted for transmitting the class-specific cell configuration parameters to the user equipment.
  • the user equipment messaging means is further adapted for receiving a handover request from the user equipment.
  • the network element further comprises a handover means for initiating a handover of the user equipment from the cell to a neighboring cell where the handover request is received.
  • This embodiment is particularly advantageous because the user equipment could be responsible for making handover decisions in some embodiments.
  • the user equipment makes handover requests, but the class-specific cell configuration parameters are used at least as a partial criterion for deciding when a handover request is made. This allows for improved management of connections between user equipment and the cellular telecommunications system.
  • the network element further comprises a cell boundary modification means for modifying cell boundaries for the user equipment using the usage message and the neighboring cell usage message.
  • the change in the cell boundary is a measure of the geographical region serviced by a cell.
  • the cell boundaries may be defined indirectly: the cell boundaries may be defined by handover parameters and/or the inter-cell interference coordination parameters and/or the transmission power.
  • the set of class-specific cell configuration parameters may comprise the handover parameters and/or the inter-cell interference coordination parameters and/or the transmission power in this embodiment.
  • the cell boundaries may be different for different classifications of user service requests. For example, services such as voice may be given to a geographical region closer to the cell so that it is less likely that there are errors in transmission or reception when using the cellular telecommunications system.
  • the user profile specifies a minimum quality of service.
  • the minimum quality of service could be a guarantee for a certain data transfer rate.
  • the minimum quality of service could be a guarantee of a maximum number of failures in data transfer for a specified time period. For instance a gold level service may specify that there s a low probability of voice service being dropped. For silver and bronze levels of service progressively higher levels of drop off or failures in a system may be allowed.
